Watering Plants with Soapy Water
If the option exists, watering plants with fresh, clean water is always the preferred choice. Only when normal water sources are not available should alternatives such as soapy water be considered.
Using Soapy Water as an Insecticide
A commonly used “home remedy” for garden pests such as aphids, mealybugs, and spider mites is a mixture of water and dishwashing liquid. While liquid soaps can be quite effective in killing soft-bodied insects, the soaps do not discriminate between harmful pests and beneficial bugs, neutralizing both in short order.
Conclusion
Soaps clean the things people use in everyday life and provide a measure of protection from illness and harm. For plants, certain types of soapy water may provide life-giving sustenance in dire situations, and insecticidal soaps may keep voracious pests at bay.
Kill Your Garden
Soaps and detergents are toxic to plants. A strong solution of soapy water sprayed onto foliage can disintegrate the leaves' waxy coating, resulting in water loss and the eventual dehydration death of the plant.
Control Weeds
Soap isn't picky. It'll kill the plants you don't want as surely as the ones you do. To make an herbicide that will do in your weeds without damaging the environment, mix 5 tablespoons of dishwashing liquid or liquid hand soap into a quart of water. Coat weeds well and soon enough they'll wilt.
Control Pests
You may be wondering why anyone would want to spray soapy water on garden foliage. Mites and aphids are two very good reasons. Soap kills small, soft-bodied insects the same way it can kill plants: it penetrates and dissolves the protective wax coating the insect, and they lose water. It can also disrupt the insects' cell membranes.
Insecticides
Liquid black soap is used to control aphids, scale insects, red spiders, whiteflies, psyllids and other thrips. It is a contact insecticide; it kills the larvae and cleans the honeydew that gulps down the leaves.
Wetting
In treatments for cryptogamic diseases, liquid black soap can also be used as a wetting agent. A wetting agent is a product that facilitates the dispersion and penetration of a water-based liquid preparation. This makes the treatment more effective and less sensitive to leaching.
Cleaner
Plants sometimes need to be cleaned; this is particularly the case for fruit trees or roses affected by fumagine, a black mold that regularly affects “aphid” plants and causes leaves to fall. To remove the carbonaceous deposit, clean them with warm water and black soap.
